  • Familiarity with CI/CD pipelines and automation tools such as GitLab, Jenkins, Docker, and pytest, supporting consistent and efficient software delivery

  • Ability to apply secure coding and fault-tolerant design principles to software development, ensuring reliability and resilience in mission-critical contexts

  • Working knowledge of spacecraft subsystems including ADCS, EPS, communications, and payload systems, and how software interfaces with and supports each

  • Awareness of European space engineering standards such as ECSS, and their practical implications for software development, documentation, and compliance

  • Understanding of RTOS concepts and their application in embedded and space software environments

  • Demonstrated familiarity with software verification and validation processes, including testing strategies and traceability requirements for mission-critical systems

  • Awareness of fault detection, isolation, and recovery principles, and how these inform robust software design in space applications
